However noinstr is always defined, regardless of # ARCH_WANTS_NO_INSTR, so there's no need to select it just for that. # # As PeterZ says [1]: # Note that by selecting ARCH_WANTS_NO_INSTR you effectively state to # abide by its rules. # # As of now the powerpc code does not abide by those rules, and trips some # new warnings added by Peter in linux-next. # # So until the code can be fixed to avoid those warnings, disable # ARCH_WANTS_NO_INSTR. # # Note that ARCH_WANTS_NO_INSTR is also used to gate building KCOV and # parts of KCSAN. However none of the noinstr annotations in powerpc were # added for KCOV or KCSAN, instead instrumentation is blocked at the file # level using KCOV_INSTRUMENT_foo.o := n. # # [1]: https://lore.kernel.org/linuxppc-dev/Y9t6yoafrO5YqVgM@hirez.programming.kicks-ass.net # # Reported-by: Sachin Sant <sachinp@linux.ibm.com> # Suggested-by: Peter Zijlstra <peterz@infradead.org> # Signed-off-by: Michael Ellerman <mpe@ellerman.id.au> # < /opt/cross/kisskb/korg/gcc-5.5.0-nolibc/powerpc64-linux/bin/powerpc64-linux-gcc --version # < /opt/cross/kisskb/korg/gcc-5.5.0-nolibc/powerpc64-linux/bin/powerpc64-linux-ld --version # < git log --format=%s --max-count=1 e33416fca8a2313b8650bd5807aaf34354d39a4c # < make -s -j 24 ARCH=powerpc O=/kisskb/build/powerpc-fixes_powernv_defconfig+NO_PERF_powerpc-gcc5 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-5.5.0-nolibc/powerpc64-linux/bin/powerpc64-linux- powernv_defconfig # Added to kconfig CONFIG_PERF_EVENTS=n # < make -s -j 24 ARCH=powerpc O=/kisskb/build/powerpc-fixes_powernv_defconfig+NO_PERF_powerpc-gcc5 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-5.5.0-nolibc/powerpc64-linux/bin/powerpc64-linux- help # make -s -j 24 ARCH=powerpc O=/kisskb/build/powerpc-fixes_powernv_defconfig+NO_PERF_powerpc-gcc5 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-5.5.0-nolibc/powerpc64-linux/bin/powerpc64-linux- olddefconfig # make -s -j 24 ARCH=powerpc O=/kisskb/build/powerpc-fixes_powernv_defconfig+NO_PERF_powerpc-gcc5 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-5.5.0-nolibc/powerpc64-linux/bin/powerpc64-linux- arch/powerpc/kernel/head_64.o: warning: objtool: end_first_256B(): can't find starting instruction arch/powerpc/kernel/optprobes_head.o: warning: objtool: optprobe_template_end(): can't find starting instruction Completed OK # rm -rf /kisskb/build/powerpc-fixes_powernv_defconfig+NO_PERF_powerpc-gcc5 # Build took: 0:04:59.723980
